CVE-2026-93435— redis-parser through 3.0.0 Denial of Service via Unbounded Recursion

Quick assessment

Affected
NodeRedis redis-parser
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

redis-parser 版本 3.0.0 及之前存在拒绝服务（DoS）漏洞，位于 RESP 协议解析器中。恶意 Redis 端点可以通过嵌套数组引发的无限制递归导致客户端进程崩溃。攻击者可以发送特制的 RESP 字节流，其中包含重复的数组头部，从而耗尽 V8 调用栈，导致未捕获的 ，进而终止 Node.js 进程，且不会触发错误处理回调。

Vulnerability Title
redis-parser through 3.0.0 Denial of Service via Unbounded Recursion
Source: CVE Program / CVE List V5
Vulnerability Description
redis-parser through 3.0.0 contains a denial of service vulnerability in the RESP protocol parser that allows malicious Redis endpoints to crash the client process through unbounded recursion on nested arrays. Attackers can send crafted RESP byte streams with repeated array headers that exhaust the V8 call stack, causing an uncaught RangeError that terminates the Node.js process without triggering error handling callbacks.
